My wedding ring is made of tungsten. It's good to know that if I ever am dipped in lava atleast my ring will be ok.
That's true, but on space craft you *need* to use materials that will melt or evaporate/burn off.
The heat is so intense, that you can't shield against it, you actually need to dump it - The space shuttle tiles vaporize during re-entry, forming a cushion of combustion gases that shield the underlying tiles from the heat of re-entry, while the gas carries the heat away from the tiles below.
Inconel, Vascomax, Hastelloy, and the other superalloys are usually designed for high-temperature creep and corrosion resistance, and/or chemical resistance, not melting point.
Without knowing what the boss intends, it's kind of hard to make suggestions, though.

I think he plans to start an earthquake designed to trigger a volcanic eruption and cover the world in liquid hot mag-ma. *pinkie*

I bent my wedding band lifting weights, so your band is good for other purposes too. And don't forget a titanium band saved Ed's life in the Abyss

Since material was mentioned and not element that does open up the arena more. Melting would have to be qualified as scientific melting or subliming...diamond would win the former and not be able to be melted outside of a extreme pressurized environment.
I don't know if you HAVE to be able to melt it to qualify for this question...that's why I said the sun originally.
Tungsten is a textbook answer if asked what elemental metal, and carbon if asked what element. I think there are some radioactive elements that melting points have not been able to be measured due to life probably.

It's also extremely good at opening beers when I can't find an opener. I read somewhere that tungsten is 8x harder then steel and 4x harder then titanium... not a scratch on it and I've opened quite a few beer bottles with my ring.

She meant it was the first time the steel in a building that was on fire has ever melted causing a collapse.

odd, despite her stupid douchery, i thought she was making good sense until the Sept 11 comments. and the blond is hot.

Depends on the tungsten ring..not all are created equally.
At what point does she say it because after the :30 mark I stopped. I can't stand Rosie's voice at all.

diamond is 3550, just a hair below tungsten. never heard of tantalum halfnium carbide.. pretty slick though, for such a high melting point.
edit: the reason why nickel super alloys are used in jet turbine blades is because of creep strength and fatigue abilities, as jagec mentioned. tungesten is also significantly more dense than nickel, as well as its alloys. so while a tungsten alloy or ceramic may have superior properties to the nickel super alloys, the extra mass (among any other property discrepancies) will significantly affect the turbine blades or other parts.

Also for those saying that carbon isn't used on the space shuttle, you fail, its what is used on the leading edges and nose.
